GARRIsoN-E. WILsoN, oF oALn'wnLL, Kansas;

To all whom'it may concern:

Be it known that I. GAnRIsoN E. W'ILson' a citizen of the United States, residing at Caldwell, in the county of Sumner and State of Kansas, have invented certain new and usefullmprovements in a Chain Sickle, of which the following is a specification.

My invention relates to new and useful im rovements in sickles and more particularly to a chain sickle.

The principal obj ect ot the invention is the provision of a device of this character which is simple and'inexpensive in construction,

and which may be driven from various types of harvesters or other machines.

Another object of the invention resides in .the construction of the frame in such a manner that the parts will be assembled in compact form.

, A further object consists in the provision of novel means for mounting the chain with the sickle blades thereon.

With these. and other objects in view my invention consists in the novel details of construction and arrangement of parts which will be more clearly understood from the following specification and drawings. in

which:-

Figure 1 is a front elevation.

Figure 2 is a top plan.

Figure 3 is a longitudinal vertical section on the line 3-3 of Figure 2'looking in the direction of the arrow. 7 V

Figure 4 is a transverse vertical section on the line 4-4 of Figure 1 looking in the direction of the arrow.

Figure 5 is a fragmental detail perspective of the chain and manner of connecting the blades, and

Fi re 6 is a transverse the line 6-6 of Figurel.

In carrying out my invention I provide runners 1 and 2 which are connected intermediate their ends by a 'bar 3 which is preferably integral although it will be unvertical section on derstood that it might be made of a separate ground. The runner 1 is beveled at the forward end and the runner 2 is beveled as indicated at 5. While this'is the preferable shape of the runners it will be understood that they might equallyas wellbe of o her shapes. 7

Specification of Letters BatentrPatefitd -1\Iar '14,- 1922, Application filed September 9, 1913. Serial No. 322,603. i I

Arecess s is formed inthe' appease of runner 1 and a sprocket wheel 9 is rotatably mounted upon this bolt ;and received inth'e' recess 6. As clearly illustrated in Figure 7 3 or" the drawings the recess 6 is of suiiicient 'depth to receive the sprocket; A nut 10 is adapted to be received-on the threadedend ot the bolt 8 to hold thesproc'ket wheel securely in, position A'shaft 11, provided with the enlarged head 12, passes through, the runner 2 and carries a sprocket wheel 13 which. is received in the recess "7. As

stated for the recess 6 this recess 7 is of sufiicient depth to receive the sprocket wheel 13. Suitablepower may be applied m the shaft 11 fordriving the-sprocket'wheel 13.

A bar 14 is securedto-the forward end of the runner 2-and as shown is offset so as to extend. over the sprocket wheel 13.' i

This bar 14 is providedqvithan opening through which the -shaft"1 l {is adapted-to for the shaft 11; Q A sprocket-chain- '15, of usual construction, is adapted to pass 'around'the sprocket This bar torms a guide and support 7' wheels '9 and 13 and operate 'in'gtihe recesses as shown. wAs' ism'ore particularly 1llustrated: in Figure 2"of the, drawing the sprocket wheel 9 is preferably of less di-I ameter than the sprocket wheel 13 so that the chain will operate at a Blades 16 are secured to the upper edge Ofthe chain 15 and when the chain'is "operated by the sprocket wheel these blades will extend over-the tops of the runners 1 and2f' slight angle. 7

It will also be noted that the bar 14 is. so Y spaced as .to allow the blades to pass there between. A bar 17 is connected to the runners 1 and 2, at the rear end, and as shown.

The-

the blades 16 operate over this bar.

bar 17' will tend to hold the blades in I straight or' horizontal position and prevent sagging of the chain intermediate the sprocket wheels. 7 r

Guard.teeth 18 are provided for protecting the blades andproperly guiding the ma proterial to be cut. Theseguards 18 are videdv with anextension 19 adapted to be secured to the underside of the connecting bar 3. The'guards are also provlded'with the shoulder 20 forming a space for the,

chain 15 to operate.- A; longitudinal recess 21 is formed in these guards to allow the blades 16 to operate therein.

From the above detailed description it is thought that the operation and advantages will be understood. It will be seen'tha t I have constructed the sickle in such a manner that the parts will be compact and take up little room. At the same time it will be seen that the several parts are protected so that danger of breakage is reduced to a minimum. .In operation power is applied to the shaft 11 and this operates the sprocket wheel 13 which in turn rotates the chain 15.

,The rotation of the chain 15 rotates the sprocket wheel 9 upon the bolt 8. The guards 18 protect the blades 16 and, as

. previously stated, the connecting bar 17 prevents sagging of the chain intermediate the sprocket wheels. Theirecesses in the runners provide sufficient space for the sprocket wheels to be received therein and for the sprocket chain to operate around the sprocket wheels.

The sickle may be used in connection with harvesting machines or any type of ma- :chine desired where power may be secured for operating the shaft 11.

The foregoing description andthe drawings have reference to what may be considered the preferred, or approved, form of my invention. It is to be understood that I may make such changes in construction :and arrangement and combination of parts,

materials, dimensions, etc. as may prove expedient and fall within the scope of the appended claims- Having thus fullydescribed my invention, what I claim as new and desire to secure by Letters Patent, is

1. A sickle comprising spaced runners,

each of said runners having a recess formed cured to one of the sprocket wheels and extending through the bar.

2. A sickle comprising spaced runners, each of which has a recess formed in the upper face thereof, a bar connecting the runners intermediate their ends, a sprocket wheel rotatably mounted in each recess, achain surrounding the sprocket wheels,-

blades secured to the chain, guards secured to the connecting bar and extending over the blades, a second bar secured to the top of the rear ends of the runners, the blades adapted to pass over the tops of. the second mentioned bar, and means for rotating one of the sprocket wheels.

3. A sickle comprising spaced runners, each of which has a recess formed in the upper face thereof, a bar connecting the runners intermediate their ends, a sprocket wheel rotatably mounted in each recess, a chain surrounding the sprocket wheels, blades secured to the chain, guards secured to the connecting bar and extending over the blades, a second bar secured to the top of the rear ends of the'runners, the'blades nerand overlying one sprocket wheel-, 'and a shaft secured to one of the sprocket'wheels and extending through the bar. I

In testimony whereof I afiix my sig'nature in presence of two witnesses.
